Sardar Sarovar, an imposing gravity concrete dam standing 136 meters high with a crest length of 1300 meters, underwent significant instrumentation upgrades. Originally equipped with over 300 Huggenberger sensors with Carlson technology installed around 1994, in 2021, we conducted a functional test of these existing instruments. Subsequently, we upgraded the system from manual to semi-automatic by installing Hek-Mux Boxes.
Following rehabilitating existing shafts in 2022, we installed new 76-meter-long plumb lines featuring direct pendulums. Additionally, we supplied automatic Telelot VDD2v4 systems tailored for measuring the dam’s horizontal deformations. These enhancements mark a substantial improvement in monitoring capabilities, ensuring the safety and efficiency of the Sardar Sarovar dam in India.
